F-CO Tape No.1

F-CO Tape No.1 is a self-bonding insulating tape for fillingup cable joints and terminals.

The tape is composed of a butyl rubber base compound and has separator.

This tape is used in combination with F-CO Tape No.2.

(Note)Be sure to wrap F-CO Tape No.2 on it to ensure the insulating property.


It is used as a filler for the part of an object requiring insulation where it would be difficult to use F-CO Tape No.2.


  1. Perfect self-bonding
    Adhere perfectly to the adhesion layer of F-CO Tape No.2
  2. Ideal hardness for filling
    Able to be shaped with fingers and easy to fill

How to use

  • Clean the surface of the object to be wrapped. While peeling off the separator, wind the tape half-lapped, and stretching it evenly to the extent that its width decreases by 1-2 mm for 20mm tape.
  • In case of filling, shape the tape appropriately before application and apply it carefully and tightly. In cold season, warm up the tape (+5°C+30°C) before application.
(Note)To improve the product, the specifications may be changed without any notice.
